Due to the low precision of speed acquisition and the limited search ability of modeling algorithms, it is difficult to obtain a highly precise fitness running model by applying the Brzostowski method. In this paper, we propose a speed acquisition and evolutionarymodeling method for fitness running that is based on the smart phone. First,we introduce a fitness running speed acquisition method based on multiple smartphone sensors and a median filter that can remove the impulse noise of three-axis acceleration signals.This noiseisgenerated by the intermittent gesture changes associated with the use of smartphones.In addition, this method can filter out the gravitational component in three-axis acceleration.Next, we designed an evolutionary modeling algorithm to enlarge the search space to obtain a better fitness running model. The experimental results show that the proposed approach can obtain more accurate speed and fitness running models than the Brzostowski’s approach.
